Description

Dispenser

The invention relates to a dispenser, in particular to a glue injector of a dispenser.

Existing dispensers typically include a controller, a glue hose that holds the glue, a gas tube that connects the controller to the glue hose, and a needle that is attached to the glue hose. The controller is used to control the amount of gas entering the glue pipe from the air pipe, thereby controlling the amount of glue discharged from the needle. However, during use, it was found that the temperature inside the hose gradually increased, which led to a gradual increase in the amount of spitting per needle, resulting in instability of the dispensing amount.

In view of this, it is necessary to provide a dispenser that can stabilize the dispensing amount.

The dispenser includes a controller, a syringe, a gas pipe connected between the controller and the syringe, and a needle fixed to the syringe, the syringe including a glue pipe and a heat dissipating component partially inserted into the glue pipe, the heat dissipating component a through hole for connecting the air pipe and the glue pipe is fixed, the needle is fixed on the glue pipe, and the controller controls the amount of glue discharge on the needle by controlling the amount of gas entering the pipe into the syringe, the heat dissipation The assembly is made of a material that is thermally conductive, and the heat dissipating assembly includes a heat conductive member disposed in the water pipe, a conductive member fixed to the heat conductive member, and a heat sink fixed to the conductive member. The heat conducting member includes a heat conducting rod for absorbing heat in the glue pipe, a fixing portion fixed to the conductive member, and a connecting portion connecting the heat conducting rod and the fixing portion. a first airflow through hole is defined in the fixing member, and the connecting portion is connected to the rubber water pipe and the first a second airflow through hole of the airflow through hole. The heat in the glue pipe can be transmitted to the conductive member through the heat conducting member and finally dissipated through the heat sink.

In the above dispenser, the heat generated in the glue pipe can be absorbed and dissipated by the heat-dissipating component made of a material that is easy to conduct heat, thereby achieving the purpose of stabilizing the temperature inside the glue pipe, and ensuring the amount of glue discharge per needle.
